Primary leptomeningeal lymphoma of the lumbar spine CSF cytology and HIV serology were both negative. EMG, however, confirmed the clinical findings of polyradiculopathy. T1W and T2W MRI of the lumbar spine demonstrated diffuse thickening of the nerve roots of the cauda equina, which enhanced following intravenous gadolinium administration (Figs. 1 and 2). No parenchymal involvement was seen.

- MRI is the imaging study of choice and slightly more sensitive than CT (66%) because of the use of paramagnetic contrast agents. Although seldom indicated, myelography may show nodularities or thickening of the nerve roots in approximately 25% of patients with LC, with similar findings apparent on MRI. Myelography can show intra-arachnoid nodular filling defects, longitudinal striations, prominent and crowded nerve roots of the cauda equina, or scalloping of the subarachnoid space.

Spinal Nerves The posterior root is the afferent sensory root and carries sensory information to the brain. The anterior root is the efferent motor root and carries motor information from the brain. The spinal nerve emerges from the spinal column through an opening (intervertebral foramen) between adjacent vertebrae.This is true for all spinal nerves except for the first spinal nerve pair (C1), which emerges between the occipital bone and the atlas (the first vertebra).Thus the cervical nerves are numbered by the vertebra below, except spinal nerve C8, which exists below vertebra C7 and above vertebra T1.The thoracic, lumbar, and sacral nerves are then numbered by the vertebra above.he posterior root is the afferent sensory root and carries sensory information to the brain. The anterior root is the efferent motor root and carries motor information from the brain. The spinal nerve emerges from the spinal column through an opening (intervertebral foramen) between adjacent vertebrae.

Lumbar spinal stenosis Lumbar spinal stenosis. (Redirected from Central canal stenosis) Lumbar spinal stenosis (LSS) is a medical condition in which the spinal canal narrows and compresses the spinal cord and nerves at the level of the lumbar vertebra. This is usually due to the common occurrence of spinal degeneration that occurs with aging.

Syringomyelia Syringomyelia is a rare disorder in which a cyst forms within your spinal cord. As the cyst, which is called a syrinx, expands and lengthens over time, it compresses and damages part of your spinal cord from its center outward.Damage to the spinal cord caused by a syrinx can cause symptoms like progressive pain, stiffness, and weakness in the back, shoulders, arms, and legs.yringomyelia can develop as a complication of trauma, meningitis, hemorrhage, a tumor, or arachoiditis. Arachoiditis is a progressive inflammatory disorder that affects the arachoid or middle membrane that surrounds the brain and spinal cord.

Cervical Spondylotic Myelopathy (CSM) Cervical spondylotic myelopathy (CSM) is a compression of the spinal cord in your neck. A compression means pressure, pinching, or squeezing. Changes in the bones, disks, and ligaments of your spine can cause pressure on the spinal cord. Sometimes growths called bone spurs add pressure to the spine.

Cortical Lesions of the Tibia: Characteristic Appearances at Conventional Radiography The tibia and fibula are the most common locations. The epicenter is cortical. The appearance consists of diffuse, mature cortical thickening. Severe venous insufficiency or venous ectasia can result in tibial or fibular cortical thickening secondary to mature periosteal bone formation (Fig 27).Venous stasis is probably the most common cause of diffuse cortical thickening in the tibia.tress fracture occurs at all ages, and there is no sex predilection. The location is diaphyseal in the tibia, and the epicenter is eccentric. The appearance consists of smooth cortical thickening, sometimes associated with lucent foci.

Spinal stenosis In lumbar stenosis, the spinal nerve roots in the lower back are compressed which can lead to symptoms of sciatica (tingling, weakness, or numbness that radiates from the low back and into the buttocks and legs). Cervical spinal stenosis can be far more dangerous by compressing the spinal cord.

Failure to Diagnose and Treat Spinal Nerve Root Compression Nerve root compression results in distinctive signs and symptoms that can be traced to the intervertebral level of the compressed nerve root. Patients may report radiating pain, sensory loss and weakness, and may exhibit reduction in or loss of reflexes. Nerve root compression can range from mild to severe.

Spinal stenosis Spinal stenosis is the narrowing of the bony space (canals) through which the nerves and spinal cord pass. Arthritis can cause the facet joints and ligaments to enlarge and thicken restricting the space for the nerves to move freely. The pinched nerves become inflamed and cause pain, cramping, numbness or weakness in your legs, back, neck, or arms.

Intermediate Dorsal NERVE COMPRESSION TO THE INTERMEDIATE DORSAL CUTANEOUS NERVE By: Robert H. Sheinberg, D.P.M., D.A.B.P.S., F.A.C.F.A.S. Nerves may be compressed from tight ligaments, inflamed tendons, tumors, fracture fragments, varicose veins, scar tissue or injuries to the foot that cause the foot and ankle to be misshapen (severe flatfoot). Nerve compression may cause significant discomfort with weightbearing.

Rapid Review Pathology Treatment depends on the cause but includes symptomatic relief with NSAIDs, other analgesics, and corticosteroids. Nerve root disorders (radiculopathies) are precipitated by acute or chronic pressure on a root in or adjacent to the spinal column. The most common cause is. A herniated intervertebral disk. Bone changes due to RA or osteoarthritis, especially in the cervical and lumbar areas, may also compress isolated nerve roots. Less commonly, carcinomatous meningitis causes patchy multiple root dysfunction.

L4 nerve root compression Lumbar intervertebral disc herniation occurs most commonly at L4/5 (L5 root; 50%) and at L5/S1 (S1 root; 46.3%) interspace. Consequently, compression of the 5th lumbar nerve root is most common, with the first sacral nerve roots a close second. A reason for the frequent compression of the L5 root may be the tight fit of the L5 root in its foramen since this root has the largest diameter and its intervertebral foramen is narrower than any other lumbar intervertebral foramen.
